13. Draught regulator

Draught regulator - thermostatic regulator is equipped with a thermosetting resin knob of an adjustment field from 30 to 100°C

(fig.7).

Screw the regulator on the 3/4" opening of the front head and orientate the red index on the upper part. The lever with the

chainlet should be introduced in the regulator holder after removing the plastic lock. If the jopint which fixes the lever with the

chainlet is taken out, take care in assembling it again in the same position..

After adjusting the knob to 60°C, block the lever with the chainlet in a slightly inclined position downwards, miernym smerom

so that the chainlet will be in axis with the air gate damper. For the adjustment of the regulator that basicly depends on the

determination of the chainlet length, proceed in the following way:

- Adjust the knob at 60°C,

- burn the boiler with open air gate damper,

- when the temperature of heating water reaches 60°C, fix the chainlet in such a position that the air gate damper will be open

with the opening of cca.1mm

- Now the regulator is calibrated and it is possible to choose the desired operating temperature by a rotating head.

14. Putting into operation - directions for a service organisation

Putting the boiler into operation can be performed only by a service organisation certified for this activity.

Checking activities before start

Before putting the boiler into operation it is necessary to check:

a ) Filling the heating system with water (check by a manometer) and tightness of the set

b ) connection to the chimney - this connection can only be carried out with the approval of a chimney-sweeping company ,

to measure the draught of the chimney by a chart of fuels

Filling the heating system with water:

Water hardness must correspond to standards and

Heating systems with an open expansion tank enable a direct contact of heating water with the atmosphere. In the period of heating

expanding water in the tank absorbs oxygen that increases corrosive effects and in the same time water is evaporated significantly.

To refill, only water treated to values by STN 07 7401: 1992 can be used.

The heating system must be thoroughly rinsed, to wash out all the dirt..

During the heating period it is necessary to keep constant volume of water in the heating system. When refilling the heating set with

water it is necessary to avoid sucking the air in the system. Water from the boiler and heating system must never by drained or taken

for use except for unavoidable situations such as repairs and so on. Draining water and feeding with new one increases the danger of

corrosion and incrustation.If refilling is necessary, it can be done only to a cooled boiler to prevent breaking the elements.

After filling the boiler and heating system check the tightness of all joints..

Finishing the assembly and testing of heating must be recorded to the Letter of warranty..

Connection to the chimney :

Connection of the boiler to the chimney must be performed by the standard and with the approval of a chimney-sweeping company.

Boilers in the central heating system must be connected to a separated chimney vent. The chimney with the right draught is a basic

condition for a good operation. It influences the performance of the boiler as well as its effectivity.

Putting the boiler into operation

- Start fire

- Set the boiler to a necessary operation temperature. Recommended temperature of the outlet water is 80°C.

- Adjust the lenght of the chainlet of the draught regulator (according to the instructions for the draught regulator).

-Keep the boiler in the operation state by the proper standards.

Again check tightness of the boiler.

- Get the customer acquinted with attendance.

- Make a record into the Letter of Warranty..

in case of unsuitable hardness

it is necessary to treat water ..
